Milestone 16.7 (November 13, 2023 - December 8, 2023)

Team Capacity

  • 1 BE

Goals

We’ll monitor progress of the foreign key backfill on ci_builds this milestone. We will continue to create the necessary MRs for updating the indexes

Bigint conversion
  • Remove the triggers and integer columns for:
    • ci_stages.pipeline_id
    • ci_pipelines.auto_canceled_by_id
  • Remove the ignore rules for:
    • ci_pipeline_chat_data.pipeline_id
    • ci_pipeline_messages.pipeline_id
    • ci_sources_pipelines.pipeline_id
    • ci_sources_pipelines.source_pipeline_id

Milestone 16.8 (December 11, 2023 - January 12, 2024)

Team Capacity

  • 1 BE

Goals

We are continuing to monitor the progress of the foreign key backfill on ci_builds this milestone. Improvements to backfill progress were made for a significant impact following the partitioning of ci_builds last milestone. It now looks like the backfill should complete within 6 weeks rather than 6 months. As such we are pulling the planned work up. After discussion with the database team, it seems like we are good to go ahead and swap the primary key column on ci_pipelines before the backfill on ci_builds completes. As such we intend to complete that in 16.8. This will allow us to move forward with partitioning of ci_pipelines while the backfile contines.

Bigint conversion
  • Remove the ignore rules for:
    • ci_stages.pipeline_id
    • ci_pipelines.auto_canceled_by_id
    • ci_pipeline_variables.pipeline_id
  • Swap columns for ci_pipelines.id

Milestone 16.9 (January 15, 2024 - February 9, 2024)

Team Capacity

  • 1 BE

Goals

Backfill of bigint Pipeline FKs is projected to finish near the end of January 2024. As such we should be able to create the indexes and foreign key constraints for p_ci_builds.

Bigint conversion
  • Create indexes and/or foreign key constraint and swap columns for:
    • p_ci_builds.auto_canceled_by_id
    • p_ci_builds.upstream_pipeline_id
    • p_ci_builds.commit_id

Milestone 16.10 (February 12, 2024 - March 8, 2024)

Team Capacity

  • 1 BE

Goals

Backfill of bigint Pipeline FKs is projected to finish near the end of January 2024. We should be able to remove the triggers and the integer column on ci_pipelines once the backfill is complete and the foreign key has been updated on p_ci_builds.

Bigint conversion
  • Remove the ignore rules for ci_pipelines.id
  • Remove the triggers and integer columns for ci_pipelines.id

Milestone 16.11 (March 11, 2024 - April 12, 2024)

Team Capacity

  • 1 BE

Goals

We will plan to have the MRs for next milestone ready to go in this milestone as well given Tian’s limited availability in 17.0.

Bigint conversion
  • Remove the triggers and integer columns for:
    • p_ci_builds.auto_canceled_by_id
    • p_ci_builds.upstream_pipeline_id
    • p_ci_builds.commit_id

Milestone 17.0 (April 15, 2024 - May 10, 2024)

Team Capacity

  • 0 BE (Note: Tian will be frontline responder this milestone)

Goals

Merging of the final MRs to remove the ignore rules. This should wrap up the conversion of the ci_pipelines PK. There are other tables requiring PK conversion, but they are smaller and less connected. Their completion will be planned into other team work.

Bigint conversion
  • Remove the ignore rules for:
    • p_ci_builds.auto_canceled_by_id
    • p_ci_builds.upstream_pipeline_id
    • p_ci_builds.commit_id
